Hi,

Tegra EMC driver was turned into a regular kernel driver, it also could be compiled as a loadable kernel module now. Hence EMC clock isn't guaranteed to be available and clk_get("emc") may return -EPROBE_DEFER and there is no good reason to spam KMSG with a error about missing EMC clock in this case, so let's silence the deferred probe error.

As I commented on patch10, I recommend that you add the Tegra EMC driver commit information into patch description and Looks good to me.
Hello, Chanwoo!
This patch11 and patch10 are depending on the patches 4/5 (the Tegra EMC driver patches) of *this* series, hence there is no commit information. I'm expecting that this whole series will go via tegra tree once all the patches will be reviewed and collect all the necessary acks from you, ICC and CLK subsystem maintainers.
Please feel free to give yours ack to the patches 10/11 if they are good to you :)
OK. Looks good to me Acked-by: Chanwoo Choi cw00.choi@samsung.com
Thank you! :)
